Assertion (A):`O_(2)` is stronger reducing agent than `F_(2)`
Reason (R ): `F_(2)` is more electronegative.

Options

A. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`.
B. If both `(A)` and `(R )` are correct but `(R )` is not the correct explanation of `(A)`.
C. If `(A)` is correct but `(R )` is incorrect.
D. If `(A)` and `(R )` are incorrect.

Answer

D

Explanation

Correct (A) : `F_(2)` is a stronger oxidising agent than `O_(2)` Since reduction potential of `F_(2)//2F^(ө)` is greater than the reduction potential of `O_(2)//2O^(2-)`. Moreover, `F_(2)` oxidises `H_(2)O "to" O_(2)`.
`2F(g) + 2H_(2)O(l)rarr4H^(o+)(aq)+4F^(ө)(aq)+O_(2)(g)`
